Please take a look at our ESOS training dates


Over 10,000 UK companies will require an ESOS assessment before December 2015.

Participating organisations need to appoint a lead assessor to carry out and oversee or review their energy audits and overall ESOS assessment.

Only a registered lead assessor can sign off on an ESOS report which will audit and assess the energy consumption of the organisations buildings, transport and processes.

Lead assessors can be employees or external contractors as long as they are members of an approved professional body register.

Lead assessors may engage and manage teams which could include non domestic energy assessors (DEC and EPC) so there is a great opportunity for non domestic energy assessors to take advantage of this new industry.
